      <abstract>
        <p>This paper presents an innovative approach to enhancing mathematical understanding through interactive modeling using GeoGebra software, based on holistic educational principles. The research describes the development and implementation of a comprehensive complex of dynamic mathematical models created within inter-university projects of the Kharkiv GeoGebra Institute. The complex comprises three distinct categories of models: fundamental mathematical concept visualization, transdisciplinary connections demonstration, and real-world problem-solving applications. A systematic methodology for model development was implemented, incorporating theoretical foundations of holistic education and practical considerations for efective visualization. The paper details the technical implementation using GeoGebra tools, discusses specific examples of models created, and presents the pedagogical framework for their application. Special attention is given to the development of supporting didactic materials that guide learners through active investigation using the dynamic models. The research demonstrates how this approach facilitates deeper mathematical understanding by connecting abstract concepts with practical applications and fostering active learning through visualization and experimentation. Results indicate that the developed complex of models efectively supports the implementation of holistic educational principles in mathematics education, particularly in establishing meaningful connections between mathematical concepts and their real-world applications.</p>

      <title>1. Introduction</title>
      <p>
        Contemporary mathematics education faces significant challenges in fostering deep understanding
and meaningful engagement among students. Recent studies by Vlasenko et al. [
        <xref ref-type="bibr" rid="ref1 ref10 ref11 ref2 ref3 ref4 ref5 ref6 ref7 ref8 ref9">1, 2, 3, 4, 5, 6, 7, 8, 9,

        ], Lovianova et al. [
        <xref ref-type="bibr" rid="ref12 ref13">12, 13</xref>
        ], Kramarenko et al. [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ], Kramarenko and Kochina [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ], Ponomareva
[
        <xref ref-type="bibr" rid="ref16">16</xref>
        ], Merzlykin et al. [
        <xref ref-type="bibr" rid="ref17">17</xref>
        ], Tarasenkova et al. [
        <xref ref-type="bibr" rid="ref18">18</xref>
        ], Achkan et al. [
        <xref ref-type="bibr" rid="ref19">19</xref>
        ] highlight persistent gaps in
mathematics education at both secondary and university levels. These challenges manifest in students’
dificulties with abstract concepts and their practical applications, ultimately afecting their overall
mathematical competence.
      </p>
      <p>
        The core issues in mathematical education, as identified by Bilousova et al. [
        <xref ref-type="bibr" rid="ref20">20</xref>
        ] and diSessa et al.
[
        <xref ref-type="bibr" rid="ref21">21</xref>
        ], include:
• Students’ struggle with abstract mathematical concept comprehension
• Limited ability to apply mathematical knowledge to practical tasks
• Diminishing interest in mathematics due to perceived complexity
• Failure to recognize mathematics’ role in other disciplines
      </p>
      <p>
        A fundamental challenge lies in students’ lack of holistic understanding of mathematics as both
a theoretical framework and a practical tool for solving interdisciplinary problems. As Singh [
        <xref ref-type="bibr" rid="ref22">22</xref>
        ]
emphasizes, this disconnect between abstract mathematical concepts and their real-world applications
often results in decreased motivation and engagement.
      </p>
      <p>
        The holistic educational paradigm ofers a promising approach to address these challenges. According
to Miller [
        <xref ref-type="bibr" rid="ref23 ref24">23, 24</xref>
        ], holistic education emphasizes:
      </p>
      <sec id="sec-1-1">
        <title>1. Learner autonomy and active participation 2. Integration of knowledge across disciplines 3. Connection between academic concepts and real-world experiences 4. Development of comprehensive understanding through practical application</title>
        <p>
          Computer Dynamic Models (CDM) emerge as powerful tools for implementing holistic education
principles in mathematics teaching. Research by Semenikhina and Drushliak [
          <xref ref-type="bibr" rid="ref25">25</xref>
          ] and Alessi [
          <xref ref-type="bibr" rid="ref26">26</xref>
          ]
demonstrates that CDMs can efectively:
• Visualize mathematical concepts in real-time
• Enable active exploration of mathematical relationships
• Facilitate understanding of transdisciplinary connections
• Support development of integrated thinking skills
        </p>
        <p>
          Among available mathematical software, GeoGebra stands out for its comprehensive modeling
capabilities. Study by Kramarenko et al. [
          <xref ref-type="bibr" rid="ref27">27</xref>
          ] highlight GeoGebra’s efectiveness in creating interactive
visualizations and supporting mathematical investigation. The software enables seamless integration
of geometric and algebraic representations, facilitating dynamic visualization and manipulation of
mathematical concepts [
          <xref ref-type="bibr" rid="ref28">28</xref>
          ].
        </p>
        <p>The Kharkiv GeoGebra Institute, operating within the International GeoGebra Institute network
since 2010, focuses on:
1. Promoting efective implementation of GeoGebra in mathematical education
2. Supporting research in mathematics, physics, and computer science
3. Advancing STEM education through technology integration
4. Fostering international collaboration in mathematical education</p>
        <p>This paper presents the results of an inter-university project conducted through the Kharkiv GeoGebra
Institute, focusing on developing a comprehensive complex of dynamic models for holistic mathematics
learning at the university level.</p>
